Climate change in Central Asia: Sino-German cooperative research findings

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Global Initiatives for Energy ConservationEnergy conservation is the practice of reducing energy use through smarter choices and efficient technologies. Around the world, countries are working together on initiatives to conserve energy, reduce pollution, and slow down climate change. These efforts involve using renewable energy sources, improving building designs, promoting efficient transportation, and encouraging responsible energy use at home and in industries. These global actions show how...

Wegener and the Continental Drift HypothesisIn the early 1900s, Alfred Wegener, a German scientist, proposed the Continental Drift Hypothesis, the idea that Earth’s continents were once joined together in a supercontinent called Pangaea and slowly drifted apart over millions of years. Although his ideas were not widely accepted then, later discoveries provided evidence supporting continental movement, leading to the modern theory of plate tectonics. Understanding Wegener’s hypothesis helps...

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
